Not 0x230. The SB base port has nothing to do with the CD's I/O port. On some cards, the port is 0x10 higher than the soundcard base (eg. real SB cards), on others it may be elsewhere. > Would this explain why GENERIC is still unable to see the cdrom??

Tinker with the base address for the CD - with userconfig under 2.0.5R you still have the "probe" command, so you can prod around and see if you can find it.
